 Speak program -
	if argv[1] = display name of another server, eg mac:0,
	and mac is running the server with audio extension
	then this program will record from default server,say
	bozo, and play on mac.
	If mac runs the same program and set argv[1] to bozo:0,
	then mac and bozo can have conversations on the workstations.

	typing q'<return> will get you out of the program.
